- Qualcomm Technologies, Inc. GPU powerlevels
- Powerlevels are defined in sets by qcom,gpu-pwrlevels. Multiple sets (bins)
- can be defined within qcom,gpu-pwrelvel-bins. Each powerlevel defines a
- voltage, bus, and bandwitdh level.
- - qcom,gpu-pwrlevel-bins: Contains one or more qcom,gpu-pwrlevels sets
- Properties:
- - compatible: Must be qcom,gpu-pwrlevel-bins
- - qcom,gpu-pwrlevels: Defines a set of powerlevels
- Properties:
- - qcom,speed-bin: Speed bin identifier for the set - must match
- the value read from the hardware
- - qcom,initial-pwrlevel: GPU wakeup powerlevel
- - qcom,gpu-pwrlevel: A single powerlevel
- - qcom,ca-target-pwrlevel:
- This value indicates which qcom,gpu-pwrlevel
- to jump on in case of context aware power level
- jump.
- Properties:
- - reg: Index of the powerlevel (0 = highest perf)
- - qcom,gpu-freq GPU frequency for the powerlevel (in Hz)
- - qcom,bus-freq Index to a bus level (defined by the bus
- settings)
- - qcom,bus-min Minimum bus level to set for the power level
- - qcom,bus-max maximum bus level to set for the power level
